VIBARATION MAGNETOMETER: Description: It contains a wooden box with glass windows on the sides, and a slit on the top, through which the oscillations can be observed. A stirrup in which a magnet can be placed is suspended by a fine, torsion-less fibre from the torsion head T. A plane mirror with a fine line PQ parallel to the length is fixed on the length is fixed on the base helps to count the number of vibrations made by the magnet, without parallax error as in figure. Principle: A freely suspended magnetic in a uniform magnetic field aligns in the direction of the field. When it is displaced through a small angle 'θ' in a horizontal plane and released, it experiences a restoring couple. This keeps the magnet in simple harmonic -motion.
APPLICATION OF VIBRATION MAGNETOMETER:The vibration magnetometer can be used. a To compare the horizontal components of earth's magnetic field at different places and. b T o determine the magnetic moment of a magnet and the horizontal component of the earth's magnetic field at a given place, when used along with deflection magnetometer.TO COMPARE THE HORIZONTAL COMPONENTS OF EARTH'S MAGNETIC FIELD AT TWO PLACES: Procedure: The box is rotated so that the line AB lies in the magnetic meridian with the help of a magnetic compass. A brass bar is placed in the stirrup and the torsion head is rotated so that the bar comes to rest in the magnetic meridian. Now the brass bar is removed and a bar magnet is kept in it. The magnet aligns in the magnetic meridian without any torsion in the suspension wire. This magnet of moment M is made to deflect in a horizontal plane through a small angle with the help of an external magnet and set to vibrate. The time taken for 10 oscillations is determined. It is repeated for three times and the average time 't' is taken. The time period T1 is calculated.
